    Notes: Carbonyliron Complexes of a 1,3-Dihydro-1,3-diborapentafulvene DerivativeReaction of 4,5-diethyl-1,3-dihydro-1,3,6,6-tetramethyl-1,3-diborapentafulvene (1) with tricarbonylbis(cis-cyclooctene)iron yields the tricarbonyliron complex (CO)3Fe(1) and the heptacarbonyldiiron complex (CO)3Fe(1)Fe(CO)4. The constitution of the compounds is derived from spectroscopic data (1H, 11B, 13C NMR, IR, MS).

    Description / Table of Contents: (η3-Ally)nickel(μ,η5-2, 3,-dihydro-1, 3-diborolyl)nickel(η3-allyl)(η1-ally) Triple-Decker ComplexesThe tetra- and pentamethyl derivatives 1a, b of 2,3-dihydro-1,3-diborole react with an excess of bis(allyl)nickel at low temperature to give thermolabile tris(allyl)dinickel triple-decker complexes 2a, b with the 2,3-dihydro-1,3-diborolyl ligand in bridging position. 2a is more reactive than 2b with respect to a condensation to give the quadruple-decker complex 4. The spectroscopic data (1H, 13C NMR) show that one allyl group is π-statically bound to a nickel atom, whereas the two others at the second nickel atom undergo a fast η1,η3 exchange with formation of an AMNXY spin system.
    Notes: Die Tetra- und Pentamethyl-Derivate 1a, b des 2,3-Dihydro-1,3-diborols reagieren mit überschüssigem Bis(allyl)nickel bei tiefer Temperatur unter Bildung der thermolabilen Tris(allyl)dinickel-Tripeldeckerkomplexe 2a, b mit dem 2,3-Dihydro-1,3-diborolyl-Liganden in Brückenstellung. 2a ist reaktiver als 2b hinsichtlich einer Kondensation zu dem Quadrupeldeckerkomplex 4. Die spektroskopischen Daten (1H-, 13C-NMR) zeigen, daß eine Allylgruppe π-statisch an ein Nickel-Atom gebunden ist, während die beiden anderen am zweiten Nickel-Atom einem raschen η1,η3-Austausch unter Ausbildung eines AMNXY-Spinsystems unterliegen.
